6063 aluminum sheet is a typical representative of Al-Mg-Si alloy aluminum sheet. 6063 aluminum alloy is representative of the extruded aluminum alloy sheet, the strength is lower than the 6061 aluminum alloy, extrusion is good, and is a low alloy Al-Mg-Si high plasticity alloy. There are many excellent characteristics of the 6063 aluminum sheet:

1. Heat treatment and high impact toughness;

2. Excellent plasticity can be squeezed into a complex structure of thin-walled, hollow profiles and forged into a complex structure of forgings. The quenching temperature range is wide and the quenching sensitivity is low. After extrusion and forging mold release, as long as the temperature is higher than the quenching temperature, which can be used to spray water or water quenching method.

3. Good weldability and corrosion resistance, no stress corrosion cracking tendency. In the heat treated aluminum alloy, Al-Mg-Si alloy is the only alloy that has not found the stress corrosion cracking phenomenon.

4. The surface is smooth, easy anodizing and coloring.

6063 aluminum sheet has excellent extrusion and weldability, good corrosion resistance and surface treatment. Under the condition of pressure and temperature, the plastic property and corrosion resistance are high, and there is no stress corrosion tendency. In the welding, its corrosion resistance is not reduced. Therefore, the utility model can be used as the material of complex cross section shape, and is the preferred material for building door and window profiles. After the treatment of 6063 aluminum sheet to ensure that the doors and windows, curtain wall with high wind pressure performance, assembly performance, corrosion resistance and decorative properties.
